Table 2.

Dropout report for the 2-month follow-up visit. Dropouts only occurred at the 2- month follow-up. Four patients did not attend the appointment and one patient had the language assessment but was not scanned. For age, years post onset, severity and total treatment sessions, values shown are mean (standard deviation). Language severity is based on the language subset from the FTD-CDR scale. As above, total severity refers to the sum of boxes, including language and behavior as per Knopman et al., (Knopman et al., 2008).
